DJI

RoboMaster S1.

The RoboMaster S1 is a game-changing educational robot built to unlock the potential in every learner. Inspired by DJI's annual RoboMaster robotics competition, the S1 provides users with an in-depth understanding of science, math, physics, programming, and more through captivating gameplay modes and intelligent features.

S1

Build It!

A modular design lets you build your S1 from the ground up, furthering the fun and providing hands-on experience with every screw and wire.

S1

  • Intelligent Controller

    Using a powerful CPU, the Intelligent Controller can simultaneously support functions such as low-latency high-definition image transmission, AI computing, and programming development. It also coordinates transmission seamlessly to execute command signals.

  • Blaster

    The S1 Blaster uses LED lights to outline launch trajectories for its gel beads and infrared beams. Vivid sound effects and recoil action add to the experience for an immersive battle simulation. For added safety, the Blaster uses non-toxic gel bead projectiles and even features limitations on launching rate and angle.

  • 2-Axis Motorized Gimbal

    The gimbal’s yaw/pitch rotation range is 540° × 65°, offering an expansive field of view for the FPV camera. The built-in direct drive brushless motor works together with the IMU and advanced algorithms to allow gimbal movements with a vibration control accuracy [1] within ±0.02°, delivering smooth image transmission and a precision control experience.

  • Mecanum Wheels

    The S1 comes with four Mecanum wheels, each with 12 rollers that allow omnidirectional movement and precision control. Front axes suspension allows for added versatility during operation.

  • High-Performance Motor

    The S1 comes with a customized M3508I motor that features an integrated FOC ESC with an output torque of up to 250 mN•m. Linear Hall-effect sensors with advanced algorithms allow closed-loop control for added precision. Additional safety mechanisms deliver outstanding stability.

  • Intelligent Sensing Armor

    Six intelligent armor panels cover the S1 to detect gel bead or infrared beam strikes. The referee system can analyze and communicate hit data, incorporating it into gameplay in real time.

S1

Learn By Doing!

The RoboMaster S1 bridges the digital world with the real one, bringing abstract theories to life through practical operations. The S1 supports Scratch and Python programming languages, allowing users to experience math, physics, and AI technology in a cutting-edge and inspiring way.

Scratch & Python Programming.

The S1 supports the Scratch and Python programming languages. This allows you to take your abilities to the next level, whether you are new to coding or are already on your way to becoming an expert.

    • Scratch 3.0

      Classic visual programming language used in primary and secondary schools worldwide.

    • Python

      Widely used in the field of artificial intelligence.

Powerful programming blocks enable you to explore a series of new functions with your S1. For example, new Scratch blocks for line follow allow the S1 to make turns at T-junctions and intersecting roads. Additionally, with new Scratch and Python interfaces for the speaker module, you can add musical notes to the action or even write a song for your S1 to play

Road To Mastery.

Road To Mastery.

Road to Mastery offers project-based courses that will enhance users’ understanding of programming languages. From robotics applications to AI technology, with different projects for both beginners and experts

RoboMaster Robotics Competition.

The S1 was inspired by DJI’s annual RoboMaster robotics competition. Since being founded in 2015, over 20,000 students from more than 400 schools have participated in this thrilling competition that tests wit, engineering, and problem-solving skills.

S1

The World is Your Arena.

Build your own competition arena anywhere, anytime and enjoy a variety of gameplay modes with an immersive FPV experience unlike any other. You can even record and share all the action with the touch of a button.

See the Action.

Enjoy a unique and immersive driving experience with the S1's exhilarating FPV perspective.

See The Action.

Race.

Compete against opponents on your own custom track. Unlock special skills like extreme speed by recognizing specific Vision Markers, or unleash weapons like dizziness against competitors to gain an edge and win the race.

Race.

Free-For-All.

There can only be one winner in this competition of wits and speed. Use custom skills to get an edge and defeat opponents in this thrilling melee that utilizes the S1's unique referee system and intelligent sensing armor.

Free-For-All.

Conquest.

Build your own competition arena and divide players into two teams. Set up your team strongholds, and the first team to occupy all of their opponent strongholds wins.

Conquest.

Develop Custom Skills.

In any competition, wisdom is equally as important as power. The S1 enables users to apply their classroom knowledge to compile custom coding, unlocking unique functions that will surprise onlookers and defeat competitors. With its new education concept, the S1 helps users embrace the joy of learning in new and exciting ways.
